EF 400mm f/4 DO IS II

This is a totally revised and updated lens, but its character remains unchanged: a revolutionary lens that combines super-telephoto power and fast f/4 maximum aperture with incredible light weight, making it equally at home for monopod or hand-held shooting. Perfect for motorsports, wildlife, and sports that place a premium on easily following rapidly and/or erratically moving subjects. And, it’s a practical answer for on-location fashion and even photojournalism — especially when the traditional professional answer, a 400mm f/2.8 lens, is simply too big and unwieldy. Updated optics, and updated Image Stabilization make this unique lens a great solution to many location shooting problems.
